General Elections, Non-Presidential Year

General elections in non-presidential years are often called gubernatorial elections, "mid-term," or "off-year" elections. However, there are actually more contests on the ballot than in presidential years. All statewide offices have been on the non-presidential year ballot for four year terms since 1974, when terms were lengthened from the previous two year term.

Changes in recent years include:

  • 1970: Last election for Constable and Justice of the Peace
  • 1974: Four year terms for statewide elected officials begin
  • 1978: Board of Supervisors expands to five members
  • 1986: Last separate election for Lieutenant Governor
  • 1990: First election with Governor/Lieutenant Governor elected as team
  • 2002: Library Trustees no longer on ballot
  • 2006: Township officials elected on non-partisan basis
  • 2010: First general election year with no September school election
